To all 1071/0712 it may concern.-

Be it known that I, GEORGE E. IIART, of .Vaterbury, in the count-y of New Haven, and in the State of Connecticut, have invented certain new and useful Improvements in DialiVheels; and i. do hereby declare that the following is a full, clear, and exact description thereof reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of my pillarplate and dial-wheels separated from each other. Fig. 2 is a like view of the same combined; and Fig. 3 is a central section of said plate, the dial-plate, and said dial-wheels as combined for use.

Letters of like name and kind refer to similar parts in each of the figures.

In the construction of certain kinds of watches in which the dial-wheels were not driven from a central arbor it has been customary to journal the cannon-pinion or minutes-hand pinion upon a stud that projected from the pillarplate, and to pin or otherwise secure said pinion in longitudinal position upon said stud. Such construction is, 110wever, open to many serious objections, which are sought to be obviated by my invention, which consists, principally, as an improvement in watches in which the dial is superimposed upon the pillar-plate, in a minutes hand pinion having an arbor journaled in the 'iil.lar-plate and extending out through the dial-plate, in combination with the hourswheel having a sleeve surrounding the minuteswheel arbor and journaled in the central spring in the dial-plate, substantially as and .f or the purpose hereinafter specified.

It consists, further, as an improvement in watches in which the dial-plate is superimposed upon the pillar-plate, in the recessed pillar-plate, in combination with the dialplate, the niinuteshand pinion in the recess of the pillar-plate having an arbor journaled at one end in such plate and extending up through the central spring in the dial-plate, and the hours-wheel having a sleeve surrounding and supporting the minutes-hand pinionarbor and journaled in the central opening of the dial-plate, substantially as and for the purpose hereinafter shown.

It consists, further, as an improvement in the diattrain of a watch, in a ni'inutes-hainil pinion contained between the pillarplate and the dialplate and carried by an arbor which is jonrnaled at one end in the pillarplatc and at the other supported by and jonrnaled in thehours-whcel sleeve, and which is connected with the time-train only through said pinion, substantially as and for the purpose hcrcinafter set forth.

It consists, further, as an improvement in the dial-train of a watch in which the dialplale is superimposed directly upon the pillarplate, in a minuteshand pinion and an hours-wheel between and journaled wholly in such plates, substantially as and for the purpose hereinafler described.

It consists, further,in combining with thepillar-plate and the dial-plate the minutes-hand pinion between the plates, having the lower end of its arbor jonrnaled. in the pillar-plate, the hourswhccl also between the plates having the sleeve surrounding and supporting the arbor oi'thc minutes-hand wheel and ion rnaled in the dial plate, and the intermediate combined wheel and pinion, substantially as and for the purposehereinafter specified.

it consists, finally, as an improvement in watches,in the dial-plate, thehonrs'whccl having the sleevcjournaled in such plate, and the minutes-hand pinion having the arbor J Olll naled in and passing through the sleeve of the hourswheel, so that the dial-train can be de tachcd from and connected with the movement by the removal and replacement of the that plate, substantially as and for the purpose hereinafter shown.

In the application of myinventiontoawatchmovement the pillar plate A is provided at its center with a recess, a, for the reception of a minutes-hand pinion, i3, and with asecond inore-shallow recess, a, for the reception of an hourswheel, G, and an intermediate wheel, D, and pinion (Z, for connecting said hours-wheel and cannon pinion. vided with an arbor, b,which, atitsinner end, has a pivot, 7), that fits into a corresponding bearing in the plate A, while above said pinion said arbor is straight, and has suchlength as to cause it to project through a dial, E, a

The pinion B is pro 1 projects from the plate A. The minutes-hand distance sufficient to enable it to receive a minutes-hand, F, upon its end. The hourswheel C is j ournaled interior] y upon the arbor b of the minutes-hand pinion I3, and exteriorly near the outer end of its sleeve 0, within the center opening, a, of the dial E, and said end projects through said opening a sufficient distance to enable it to receive an hours-hand, G, by which arrangement the outer end of said arbor is effectively journaled and held in lateral position. The intermediate wheel and pinion, D (l, are journaled in the usual manner upon a stud, a", that is secured within and pinion B is engaged by one of the wheels of the time-train and caused to revolve once each hour, and through the intermediate wheel, D, and pinion 11 causes the hours-wheel G to revolve in the same direction, but with but onetwelfth the velocity. The end-shake of said minutes hand pinion and hours-wheel is determined by the space between the upper end of the hub 0 of said wheel and the lower face of the dial E, and maybe varied by increasing or diminishing the height of said hub, or by recessing the contiguous portion of the face of said dial. \Vhen the hands F and G are in position upon the arbor ofpinion B and sleeve of. hours-wheel G, the pinion and wheel are held connected with the dial E, and may be placed in or removed from position with said dial, by which meansthe removal of said hands is avoided when tals ing down the watch-movement. As there is no axial opening required for said -minuteshand pinion, its arbor or barrel may be made much smaller than would otherwise be possible, and its size renders available a smaller sleeve or barrel for the hourswheel.

Having thus fully set forth the nature and merits of my invention, what I claim is- 1. As an improvement in watches in which the dial is superimposed upon the pillar-plate, a minutes-hand pinion having an arbor journaled in the pillar-plate and extending out through the dial-platc, in combination with the hours=wheel having a sleeve surrounding the minutes-wheel arbor andjournaled in the central opening in the dial -plate, substantially as and for the purpose specified.

2. As an improvement in watches in which the dial-plate is superimposed upon the pillarplate, the recessed pillar-plate, in combination with the dial-plate, the minutes-hand pinion in the recess of the pillar-plate, having an arbor journaled at one end in such plate and extending up through the central opening in the dial-plate, and the hours-wheel having a sleeve surrounding andsupporting the minutes-handpinion arbor and journaled in the central opening of the dial-plate, substantially as and for the purpose shown.

3. As an improvement in the dial-train of a watch, a minutes-hand pinion contained between the pillar-plate and the dial-plate, and carried by an arbor which is journaled at one end in the pillar-plate, and at the other supported by and journaled in the hours-wheel sleeve, and which is connected with the timetrain only through said pinion, substantially as and for the purpose set forth.

4. As an improvement in the dial-train of a watch in which the dial-plate is superimposed directly upon the pillar-plate, a minutes-hand pinion and an hours-wheel between and journaled wholly in such plates, substantially as and for the purpose described.

5. In combination with the pillar-plate and the dial-p1ate, the minutes-hand pinion between the plates, having the lower end of its arbor journaled in the pillar-plate, the hours-wheel also between the plates, having the sleeve surrounding and supporting the arbor of the minutes-hand wheel and journaled in the dialplate, and the intermediate combined wheel and pinion, substantially as and for the purpose specified.

6. As an improvement in watches, the dialplate, the hours-wheel having the sleevejournaled in such plate, and the minutes-hand pinion having the arbor journaled in and passing through the sleeve of the hours-wheel, so that the dial-train can be detached from and connected with the movement by the removal and replacement of the dial-plate, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of June, A. D. 1885.
